Obviously, according to future Venom headlines, Flash Gordon is here to stay for a nice lengthy run with the symbiote. He will be featured in many stories coming up, being involved with way more than just Spiderman, but with the Secret Avengers, as well as X-23, Red Hulk, and (SHE-) Ghost Rider on a temporary team up.
But, we all know how long hosts last for Venom... I mean, I still think of Eddie Brock as the original Venom, but we all known how often that symbiote gets passed around. I think it's inevitable that the symbiote continue to infect numerous characters and never fully settle on one person.
I, personally, would like to see a story arc or something of the new Scarlet Spider, Kaine taking up the symbiote as a "Scarlet Venom" for a little while... but my point here is that even though I 100% hope we get to see Kaine as Venom one day, and how much I'd love to see Eddie Brock get the symbiote back for some more original Venom stories, I really think Flash Gordon as Venom is a huge development to Venom, and Venom can now become known for something more than being that wicked black symbiote with a ridiculously long, slimy tongue, that talks about himself as if he is multiple people at once.
